Use

(1) Continuous method for preparation of choline chloride solution: continuously send the trimethylamine hydrochloride and a certain amount of ethylene oxide separately through pump into the reactor; the reactants had a residence time at the reactor of 1-1.5h; the reaction was carried out under stirring and has its resulting product being continuously withdrawn so that the liquid level within the reactor remained stable. The withdrawn choline chloride extraction crude product entered into the stripper to obtain 60-80% choline chloride liquid product from the bottom. (2) Trimethylamine hydrochloride was reacted with ethylene oxide, and then added with an organic acid for neutralization and further concentration to obtain the choline chloride (3) Chloro-ethanol was reacted with trimethylamine to generate choline chloride. (3)Ethylene oxide method. It can be made from the reaction between ethylene oxide and trimethylamine. Add the trimethylamine ethanol solution into the reactor, send through ethylene oxide at about 30 ℃ and stirring reaction of 4 hour and further obtain it through neutralization with hydrochloric acid (control PH at 6.5-7.0). The yield of the crude product can be as high as 98%. The crude product can further be subject to activated carbon decolorizing and vacuum concentration to obtain 70% aqueous solution. The aqueous solution was added with ground corn cobs, rice hull flour, wheat bran or diatomaceous earth and some other kinds of excipients and can give 50% of the powder. (4) Chlorohydrin method. Use chlorohydrin to substitute ethylene oxide and hydrochloric acid; have it reacted with trimethylamine in the presence of a small amount of ethylene oxide or alkaline substance; First add 100 parts of chlorohydrin into the reaction vessel, further add 130 parts of trimethylamine from the liquid surface, while supplying 1.7 parts of ethylene oxide to trigger the reaction. After the addition, stir at 32-38 ℃ for 4h with the yield being 84% (calculated from chlorohydrin). For example, if catalyzed with an alkaline substance (such as quaternary ammonium salts), the one-way conversion rate can reach over 97%. Trimethylamine methanol solution and chlorohydrin is subject to heating reaction, concentration under reduced pressure, and re-crystallization to generate it.
